  • Analyzing Vulnerability of Asynchronous Pipeline to Soft Errors:
           Leveraging Formal Verification
    • Abstract: Abstract Glitches due to the secondary neutron particles from cosmic rays cause soft errors in integrated circuits (IC) that are becoming a major threat in modern sub 45nm ICs. Therefore, researchers have developed many techniques to mitigate the soft errors and some of them utilize the built in error detection schemes of low-power asynchronous null conventional logic (NCL). However, it requires extensive simulations and emulations for careful and complete analysis of the design, which can be costly, time consuming and cannot encompass all the possible input conditions. In this paper, we propose a framework to improve the soft error tolerant asynchronous pipelines by identifying and formally analyzing the vulnerable paths using the nuXmv model checker. The proposed framework translates the design behavior and specification into a state-space model and the potential vulnerabilities against soft errors in the pipeline as linear temporal logical (LTL) properties. These formally specified properties are then verified on the state-space model and in case of failure counterexamples are obtained. These counterexamples can then be further analyzed to obtain the soft error propagation paths and thus give insights about soft error tolerant approaches to the designers. For illustration, this work provides an analysis and comparison of three state-of-the-art asynchronous pipelines. Formal model and analysis of all the pipelines show that the soft error hardened pipeline is comparatively superior against soft errors but at the expense of almost two times area overhead.

  • A Novel Compact Model for On-Chip Vertically-Coiled Spiral Inductors
    • Authors: Bing Hou; Tong Liu; Jun Liu; Junli Chen; Faxin Yu; Wenbo Wang
      Abstract: Abstract A novel compact model for on-chip vertically coiled spiral inductors is presented. The vertical metal coils are modeled by a ladder network consisting of ideal inductors and resistors. The skin and proximity effects are taken into consideration. The capacitive parasitics between relevant metal layers are modeled. A method to analytically extract the model parameters is proposed. The model prediction shows excellent agreement between the data from both simulation and measurement over the frequency range of 0.1–66.1 GHz, for a vertically coiled spiral inductor manufactured in TSMC 90 nm RF CMOS technology.

  • Path Clustering for Test Pattern Reduction of Variation-Aware Adaptive
           Path Delay Testing
    • Authors: Michihiro Shintani; Takumi Uezono; Kazumi Hatayama; Kazuya Masu; Takashi Sato
      Abstract: Abstract In this study, a novel path clustering technique for adaptive path delay testing, where the test paths are altered according to the extracted device parameters, is proposed. The proposed algorithm is based on the k-means++ algorithm. By considering the probability function of the die-to-die systematic process variation, the proposed algorithm clusters path sets to minimize the total number of test paths. A figure of merit for clustering, which represents the expected number of test paths, is also proposed for quantitatively evaluating path clustering under different conditions. The proposed clustering method is evaluated numerically by applying it to the OpenCores benchmark circuit. Using our clustering technique, the average number of test paths in the adaptive test is reduced to less than 92 % compared with those in the conventional test. In addition, adaptive testing using the proposed technique can reduce the test patterns by 94.26 % while retaining the test quality.

  • CPP-ATPG: A Circular Pipeline Processing Based Deterministic Parallel Test
           Pattern Generator
    • Authors: Kuen-Wei Yeh; Jiun-Lang Huang; Laung-Terng Wang
      Abstract: Abstract Parallel computing is widely utilized to speed up automatic test pattern generation (ATPG); however, most of today’s parallel ATPGs are non-deterministic, which often leads to non-reproducible test pattern sets. This paper presents a fault-parallel test pattern generator: CPP-ATPG; it generates the same test pattern set regardless of the thread count and timing. Besides, it exhibits good speedup scalability as the thread count increases. These are achieved by the circular pipeline processing (CPP) principle, which guides the proposed parallel ATPG to preserve the task processing orders that are necessary to ensure ATPG determinism but with low inter-thread synchronization overhead. Furthermore, a multi-round test generation and compaction strategy is proposed to avoid possible test pattern inflation. Experimental results show that CPP-ATPG exhibits close-to-linear speedup for at least up to 12 threads.

  • Optimization of Test Wrapper for TSV Based 3D SOCs
    • Authors: Surajit Kumar Roy; Chandan Giri; Hafizur Rahaman
      Abstract: Abstract Manufacturing of core based three-dimensional (3D) integrated circuit (IC) is an emerging field of semiconductor industry that promises greater number of devices on chip, increased performance and reduced power consumption. But due to scaling in technology features these chips are more complex. Hence testing of these 3D ICs is a challenging task and designing the test wrapper of core is also an important issue in this respect. This paper follows a IEEE 1500-style wrapper design for 3D ICs using Through Silicon Vias (TSVs) for testing purpose. It is assumed that the core elements are distributed over several layers of the ICs. As the number of available TSVs are limited due to small chip area, this work is intended to design balanced wrapper chains using minimum number of TSVs so that testing time of a core is reduced. In this work we have proposed a polynomial time algorithm of O(N) to design the test wrapper. The results are presented based on the ITC’02 SOC test benchmarks and compared with prior works. Obtained results show that our algorithm provides better utilization of TSVs compared to the work presented in Noia et al. (2011).

  • Current-Based Testing, Modeling and Monitoring for Operational
           Deterioration of a Memristor-Based LUT
    • Authors: T. Nandha Kumar; Haider A. F. Almurib; Fabrizio Lombardi
      Abstract: Abstract This paper presents a method for operational testing of a memristor-based look-up table (LUT) memory block. In the proposed method the deterioration of the memristors (as storage elements of a LUT), is modeled based on the reduction of the resistance range, a phenomenon well known as reported in the technical literature. A quiescent current technique is used to diagnose the memristors when deterioration results in a change of state, thus leading to a fault. In addition to testing, the proposed method can be utilized also for continuous monitoring of the memristor deterioration in the LUT. The deterioration of the memristors is modeled using a simple yet accurate equivalent circuit. The proposed method is simulated using LTSPICE and extensive simulation results are presented for operational deterioration with respect to different features such as LUT dimension, range of memristance and MOSFET feature size. These results show that the proposed test method is highly efficient for testing and monitoring a LUT in the presence of deteriorating multiple memristors.

  • A New Approach for Modeling Inconsistencies in Digital-Assisted Analog
           Design
    • Authors: Gürkan Uygur; Sebastian M. Sattler
      Abstract: Abstract Safety critical circuits and systems require a specified function and real world structure to match each other. At the same time the functionality and the structure become more and more complex. This results in a high effort for design verification and test such that specification-oriented testing is getting more and more under pressure. In this paper we offer an approach to warrant the match between a specification and its structure by invertibly composing the corresponding “fingerprint” model. Conversely, the fingerprint warrants the match between specification and structure. We present a theoretical framework for creating the fingerprint from the specification and the structure, respectively, and demonstrate the parallel composition of fingerprints to an overall asynchronous feedback circuit system.

  • Fault Diagnosis in Highly Dependable Medical Wearable Systems
    • Authors: Cristina C. Oliveira; José Machado da Silva
      Abstract: Abstract High levels of dependability are required to promote the adherence by public and medical communities to wearable medical devices. The study presented herein addresses fault detection and diagnosis in these systems. The main objective resides on correctly classifying the captured physiological signals, in order to distinguish whether the actual cause of a detected anomaly is a wearer health condition or a system functional flaw. Data fusion techniques, namely fuzzy logic, artificial neural networks, decision trees and naive Bayes classifiers are employed to process the captured data to increase the trust levels with which diagnostics are made. Concerning the wearer condition, additional information is provided after classifying the set of signals into normal or abnormal (e.g., arrhythmia, tachycardia and bradycardia). As for the monitoring system, once an abnormal situation is detected in its operation or in the sensors, a set of tests is run to check if actually the wearer shows a degradation of his health condition or if the system is reporting erroneous values. Selected features from the vital signals and from quantities that characterize the system performance serve as inputs to the data fusion algorithms for Patient and System Status diagnosis purposes. The algorithms performance was evaluated based on their sensitivity, specificity and accuracy. Based on these criteria the naive Bayes classifier presented the best performance.

  • A Wideband Digital-to-Frequency Converter with Built-In Mechanism for
           Self-Interference Mitigation
    • Authors: Imran Bashir; Robert B. Staszewski; Oren E. Eliezer; Poras T. Balsara
      Abstract: Abstract A digital-to-frequency converter (DFC) assisted by a built-in-self-measurement mechanism is presented. It demonstrates the capability to overcome oscillator pulling that is caused by the high-speed digital frequency-tuning signal that is fed into the DFC’s digitally-controlled-oscillator (DCO), thereby allowing the DFC to accommodate high-rate modulating data. Thus, by placing replica images and quantization noise far away from the transmitted carrier, the presented DFC is suitable for wireless applications having the most demanding spectral mask requirements, without necessitating RF filtering in the transmitter’s signal path. The proposed solution, designed with minimum overhead, reduces the extent of injection pulling experienced by the digitally controlled oscillator (DCO) due to ΣΔ dithering applied to its capacitor bank by adjusting the phase between the aggressor and victim signals through a digitally controlled delay (DCD) line. The proposed calibration and compensation scheme for the DCD is autonomous and simple computationally. The proposed solution has been demonstrated in a transmitter of a commercial cellular CMOS system-on-chip (SoC).

  • A 65nm CMOS Ramp Generator Design and its Application Towards a BIST
           Implementation of the Reduced-Code Static Linearity Test Technique for
           Pipeline ADCs
    • Authors: Guillaume Renaud; Manuel J. Barragan; Asma Laraba; Haralampos-G. Stratigopoulos; Salvador Mir; Hervé Le-Gall; Hervé Naudet
      Abstract: Abstract This work presents an efficient on-chip ramp generator targeting to facilitate the deployment of Built-In Self-Test (BIST) techniques for ADC static linearity characterization. The proposed ramp generator is based on a fully-differential switched-capacitor integrator that is conveniently modified to produce a very small integration gain, such that the ramp step size is a small fraction of the LSB of the target ADC. The proposed ramp generator is employed in a servo-loop configuration to implement a BIST version of the reduced-code linearity test technique for pipeline ADCs, which drastically reduces the volume of test data and, thereby, the test time, as compared to the standard test based on a histogram. The demonstration of the pipeline ADC BIST is carried out based on a mixture of transistor-level and behavioral-level simulations that employ actual production test data.

  • Reliability Analysis of Fault-Tolerant Bus-Based Interconnection Networks
    • Authors: Fathollah Bistouni; Mohsen Jahanshahi
      Abstract: Abstract Multi-processor systems need interconnection networks (INs) in order to make the connection among the processors, memory modules, and nodes. Bus interconnection network is the simplest and least expensive one among all the INs. Therefore, bus network is easily understood and preferred by manufactures for implementation. However, a bus network is inherently a non-fault tolerant and blocking network. To cope with these problems, a solution is to use several buses in parallel on a network. Based on this idea, various schemes can be designed for a bus network: (1) Multiple-bus with full bus-memory connection, (2) Multiple-bus with single bus-memory connection, (3) Multiple-bus with partial bus-memory connection, and (4) Multiple-bus with class-based memory connection. On the other hand, a metric for the efficiency of fault-tolerant systems is its reliability. Although, there is no detailed analysis of the reliability of bus-based networks, this paper presents accurate and complete reliability analysis of bus-based networks to achieve these aims: (1) Determining the most efficient design of bus-based networks in terms of reliability, cost-effectiveness, and blocking issues, (2) Providing new methods for evaluating the performance of bus-based networks.

  • Interconnect Reliability Analysis for Power Amplifier Based on Artificial
           Neural Networks
    • Authors: Qian Lin; Haipeng Fu; Feifei He; Qianfu Cheng
      Abstract: Abstract In order to learn the interconnect reliability of the complicated integrated circuit, a power amplifier 3D model is constructed and analyzed. The modeling and computation are completely automatic using the APDL. In order to predict the interconnect reliability of the power amplifier for the given design index effectively, the artificial neural networks model is used, then the prediction can be done fast. Training the simulation data from ANSYS, the neural network is used to model the relationship between the input and output. Then, a reliability database can be obtained which can help the designer to get the reliability performance of any design solution and the tradeoff decisions on the transistor’s size and the operation condition.

  • An Efficient Contact Screening Method and its Application to
           High-Reliability Non-Volatile Memories
    • Authors: Friedrich Peter Leisenberger; Gregor Schatzberger
      Abstract: Abstract In modern automotive designs double contacts are mandatory to achieve high reliability products and avoid field returns due to contact issues during the lifetime of the product. Using double contacts in compact digital IPs like RAM, ROM or NVMs leads to a dramatic area penalty. High area efficient NVMs are using shared contacts to minimize the area needed to realize the NVM bit cells. Using double contacts would lead to an area increase of approximately 50 % of the NVM memory plane. The high quality standard defined for automotive applications can only be fulfilled with a sophisticated contact screening procedure. This work will present a contact screening procedure which is able to detect contacts with a resistivity outside the main contact resistivity distribution. Those outliers have a potential danger to fail during lifetime as shown in this paper.

      Abstract: Abstract An instrument for on-chip measurement of transceiver transmission capability is described that is fully realizable in CMOS technology and embeddable within an SoC. The instrument can be used to inject and extract the timing and voltage information associated with signals in high-speed transceiver circuits that are commonly found in data communication applications. At the core of this work is the use of ΣΔ amplitude- and phase-encoding techniques to generate both the voltage and timing (phase) references, or strobes used for high-speed sampling. The same technique is also used for generating the test stimulant for the device-under-test.

  • The Faults Diagnostic Analysis for Analog Circuit Based on FA-TM-ELM
    • Authors: WenXin Yu; Yongbo Sui; Junnian Wang
      Abstract: Abstract Developing fault detection is very important for improving the equipment reliability and saving energy consumption. As compared with neural networks, extreme learning machine (ELM) is based on statistical learning theory, which has advantages of better classification ability and generalization performance. This paper presents a novel approach for fault detection and diagnosis based on Firefly-Chaos Algorithm and Extreme Learning Machine. The experiment result indicates this proposed method is effective for Analog Circuit fault detection and diagnosis and the model generalization ability is favorable.
